This 02-06 Mini Cooper intake is from Injen's original IS short ram intake line.
Injen is the intake company for people care about power above all else. They are designed to take a beating (they are much thicker than other intakes), and they use outside the box designs to optimize performance. They don't breeze through R&D to just bring a passable intake to market. They actually spend a lot of time and effort to engineer the absolute perfect intake for your Cooper.
The IS Short Ram line is a simple to install and safe intake for your Cooper. Unlike cold airs, this intake sits fairly high in the engine bay, so you don't have to worry about water ingestion on rainy days. Of all the Injen intakes, they are probably the least intrusive intake line that gives a good amount of performance without deviating too much from your stock specs.
